I have been using heavily glisseq in my latests projects and as soon as the cpu load starts to get even closer to 50%, then I cannot open any glisseq plugin without causing lots of crunching...

My guess is that this is connected to some threading/multi-core issues. I dont recall that much crunching when I had a single core CPU. Even increasing latency doesnt do anything.

I had a similar issue with wavearts plugins until their latest release that "implements a new thread synchronization mechanism so that performance issues (graphics updating, slow responsiveness in particular circumstances) are avoided". Could the underlying issue be the same with voxengo plugs?

Does this stuttering/crunching happens when you close user interface? Also, do you have XRay enabled? (if so, please try disabling it for a moment and see if this affects this problem).

This crunching happens only when the interface is open and I have not been using XRay. When the interface is closed, it works smoothly. The same crunching also happens with voxformer and in FL Studio 7 (although it is not as bad as Sonar). There is something about dual core and Sonar 6.2.1 that aggravates this issue... When I had a single core CPU (same setup), I did not experience all this crunching unless the CPU was *really* high (> 80%)

Could you temporarily turn the multi-processing off and see what happens?

So I tried pretty much everything... disabled multi processing, disabled graphic acceleration, changed the color depth and nothing to do still alot of crunching even with a low cpu usage. the one that had the most impact was changing the color depth from 32 bits to 16... it makes things a little better. I'm ready to change the video card or whatever to stop the crunching!!!
